Title: LIGHTING DEVICE FOR VEHICLES
Abstract:
The invention relates to a lighting device for vehicles, said lighting device having a housing which is closed by a transparent cover pane and in which there are a light source unit, containing at least one first and one second light source (3, 3', 3''), and an optical unit, containing a hologram element (8) for generating a holographic luminous image. The optical unit has at least one screen element (9, 9', 9'') for limiting an emission angle range (φ) of the light source (3, 3', 3''). The optical unit has a first optical component (7, 7', 7'') associated with the first light source (3, 3', 3'') and a second optical component (7, 7', 7'') associated with the second light source (3, 3', 3''), with which components light (10, 10', 10'') emitted by the light sources (3, 3', 3'') can be deflected in the direction of the hologram element (8). In a transition region (12) between the optical components (7, 7', 7''), a shielding element (13, 13') protrudes such that scattered light (15) which is emitted by the first light source (3) and does not impinge on the associated first optical component (7) is prevented from impinging on the adjacent second optical component (7') and, conversely, that scattered light (15') which is emitted by the second light source (3') and does not impinge on the second optical component (7') is prevented from impinging on the first optical component (7).
